Now that we've defined usability and have
a better understanding of it in the world
0:04
around us, we're going to explore how
it affects our online experience.
0:09
But first, let's take a look at how
usability had a evolved over the years,
0:13
along with the web and
the needs of it's users.
0:18
In one sense,
0:22
the process of going online is very
much the same as it has been for years.
0:23
Since many people still go to some sort
of computer, they open a web browser and
0:27
start clicking.
0:32
But many of the details associated
with this process are vastly different
0:33
from the early days of the web.
0:37
Visiting web sites used to mean
sitting at home or in an office,
0:40
on a large slow machine,
gazing into a giant box like monitor.
0:43
The speed of the connection varied,
0:48
as did the power of the computer and the
capabilities of the websites they visited.
0:51
Today, users can access
the web from anywhere,
0:56
through an incredible array of devices,
large and small.
1:00
They're not tied to desks,
or even homes or offices.
1:04
The power of new devices
introduced each year
1:07
often blows away the previous version, and
the speed at which they access the web
1:10
is many degrees of magnitude
faster than the years before.
1:15
At the same time,
programming languages and
1:20
web servers have evolved,
serving up websites quicker than ever.
1:22
While older sites were dominated by
text and low res images, today's sites
1:26
serve up HD quality video and
high res graphics, at a much higher speed.
1:31
With these advances in technology,
the users of the world now expect and
1:37
demand more than ever.
1:42
So as designers and developers continue
to push the envelope, users have become
1:44
accustomed to progress, and
they expect things to work, and work well.
1:49
So what does all this mean for
the state of useability?
1:55
It's become vital for designers and
developers to ensure that their sites and
1:59
apps are efficient, fast, and reliable.
2:04
Content must be accessible at all times,
no matter where users are.
2:08
And often across various channels,
such as websites and social media.
2:12
Important features and functions must be
usable on laptops and mobile devices.
2:17
Therefore, adopting a user-centered
approach to the design,
2:21
means anticipating the challenges of the
present day users, as well as the future.
2:26
Looking at our past can give
us clues on what to expect,
2:31
such as even faster access,
even more ways to access everything and
2:35
doing so on devices that we
haven't even imagined yet.
2:40
But what wont change, is that we still
have users a great first impression.
